DENVER -- Don't be surprised if the next trip through security at Denver International Airport means using a new biometric fingerprint scanner.
DIA is one of two airports in the country conducting a proof-of-concept demonstration with the devices to see how well they work in speeding up security screenings.
The technology is in the Transportation Security Administration Precheck line. Hartsfield-Jackson Atlanta International Airport is the other airport trying out the technology.
Much like using a thumbprint to access an iPhone, the biometric authentication technology would allow travelers to use fingerprints in place of a boarding pass and ID.
It would only work for passengers who previously provided fingerprints by enrolling in the TSA PreCheck screening program.
Once fingerprints are matched up, the machine would then obtain boarding pass information through Secure Flight.
All participation is voluntary. Any passengers who decide to participate will still have to provide the required boarding pass and identification.
Precheck passengers who haven't registered their fingerprints can also volunteer to use the system because all data collected are information that will be analyzed by the TSA.
"Through these and other technology demonstrations, we are looking to reinvent and enhance security effectiveness to meet the evolving threat and ensure that passengers get to their destinations safely," TSA acting assistant administrator Steve Karoly said.
The TSA will analyze the data collected in Denver and Atlanta's pilot programs in hopes of potentially implementing the technology at other U.S. airports in the future.
